Kalkulator v2.50 Опции

[rszyma]

In its simplest level, Kalkulator is a calculator. It will accept an arithmetic expression, calculate its value, display the result and store it for a later use. For example, entering

5+3*log 1000

and pressing Enter will compute and display the expression value, 14, storing it as t (the Temporary Variable, used unless you specify another one).

Instead of pressing Enter, you may use the "=" key (or the [=] button) and choose a variable from a pop-up menu; this variable will be used to store the result.

Variables can be also used as components of expressions, as in

2.5*ln(3+exp X)-sin(2A+3t)

Being able to see the whole expression before and after evaluation, you can modify and recompute it at any time.

An expression can be more than just evaluated. Treated as a function of t, it can be used to compute integrals, derivatives, sums or roots. It can be also plotted on the screen. A number of expressions can be treated as a system of nonlinear equations or ordinary differential equations to be solved.

The calculation result can be converted between various measurement units, or displayed in a selected format (for example, as a fraction or as degrees, minutes and seconds).

Kalkulator also has a data buffer to store a number of data points; it can perform some statistical operations on those points: computing population parameters, drawing histograms or scatter plots with polynomial regression. From less trivial tasks, Kalkulator does arbitrary multi-parameter curve or distribution fitting. It will also recompute, using a given formula, all X or Y values in the buffer.

A separate window is provided to perform computer arithmetic operations on integer arguments of finite bit length and to translate numbers between binary, octal, hexadecimal and decimal (signed or not) representations.

Last but not least, Kalkulator can be also used for linear algebra: vector and matrix operations. This includes solving systems of simultaneous linear equations.

Kalkulator v.2.50 — 2005/08/14

_http://www.wrotniak.com/works/kalkulator/_zip/kalkulator.zip

What's new:
New in Version 2.50 Unit conversion now uses definitions in an external file, which can be modified by the user to add new units or unit categories.
Added user-defines physical constants from a file.
Improved algorithm used to round graph limits.
Balloon hints use the font as selected for the Preferences.
Fixed documentation: wrong formula for histogram goodness of fit (the program was using the right one).
